Show off your Gems / Re: Buy Torrington Emerald
« on: March 27, 2021, 05:48:16 PM »
this is not a fishing expedition is it -looking for a large good emerald from a very specific area - after all the hulablu about restrictions /fines for fossicking in this area - just seems to me a strange request from a newbie.

Hi,  This has been a wonderful site that contains a lot of valuable/informative information - it would be an absolute travesty if access to this information is lost.  Surely it is up to us members to assist financially by way of an annual fee to cover the fixed upfront costs of hosting the forum. Looking at the statistics of who is online there is always a large number of Guests and a total of 4487 members, Now all of those members are probably not active on the site - I read it every couple of days - I know I have not been openly active as many members are, but I do contact people directly when they have asked for help or advise by way of a PM but surely there are say 100 to 300 members who would be happy with an annual fee which would give them access to the history and gallery and restrict "Guests" to index and "recent activities" for example. Thank you Makky Brown for taking up the gauntlet of trying to keep this forum open. Maybe it is a possibility to explore charging suppliers other than Aussie Sapphire a small  advertising fee particularly if we purchase from them some how thru the forum - that way they get feedback if it is worthwhile for them to advertise on the forum - just a thought.

Hi Leah,
I don't know much about "Tags" and was wondering if the "Tags" listed on this topic is creating problems as none of the names in the "Tags" section  are members? As Administrator you could remove them?

Yes you are right - my copy is also a "soft cover" - I noted that the Trove web site also listed 2 ISBN numbers - I agree with you contacting the Gold Coast club is his best bet which he can do via which gives email address, phone number and physical address

Moh's hardness test can be used to identify mineral specimens - have a look at this web site to get and understanding of Moh's test Looking at you sample unfortunately for you  it looks like glass to me. Did you go to the gem/rock display located just in the caravan park in Nundle - Tourist info place- they have information of fossicking spots in and around Nundle.

this web site states that Paul's book is a "Hardcover is a limited edition of 1000 signed and numbered copies." so it may not be re published.

This firm is currently out of stock but might be able to advise when they have new stock - this web site also identifies the ISBN of the book and it may help you chase it up with publishers.

Hi, some time ago I took off the counter balance but it was opposite the throw. Can't remember why I took it off.  Just thinking about your application - I used a 25mm drive shaft and with the 2.5mm offset could get a 20mm short stub to hold a flat flange 20mm bearing to bolt to the plate. If you have a 25mm drive shaft with your offset you would end up with a 12 to 13 mm short stub for your bearing to attach to your plate - I think it is a bit small for your size plate diameter. I think you must have a much larger drive shaft - in any case you can measure the throw by rotating the drive shaft by hand  and measure the movement of the plate from a fixed point for 1 complete rev of the drive shaft. I do occasionally have problems with large rocks where the mass of the rock is a fair distance from the plate - they tend to just want to rotate or bounce around- but no problems when the weight of the material I am polishing is low eg slabs even 2" to 4" no problem provided the surface dimensions of the slab are bigger than height ie the lower the centre of gravity the better. Interestingly enough I don't have any problems in the grinding stage with ones that give problems in the polishing stage. I use lead weights on slabs and only use 80 grit which breaks down nicely and then go direct to polishing using dry alum oxide.

Hi  I built my 24 inch dia flat lap 15 years ago with a 2.5mm offset on the shaft. So with nothing on the lap, if I put a very small amount of grit on the lap and run it  the grains of grit run around in an approximate diameter of 5mm. The machine works fine with the rocks moving both when grinding and polishing. From what you said you have an offset of 6mm on the shaft, so in your case the grits, if you did my test, would make a diameter of 12mm- which seems too much to vibration to me.

When you can move about again go for a drive to visit Aradon at Malaga - lots of polished rocks to see and you can also buy your supplies of grit there as well as well as asking for any advise. 

By the way there are a lot more than 2 wheels in a car -  flywheel and gearwheel (gearbox is full of them)

Hi Tinker,
I have some of that opal that needs treatment but haven't got around to it yet. I came across the following
and it provides excellent info how to go about treating the opal. Basically you have to preform your material then treat it and then final polish. Let us know how you go

         If you are planning to go to Mount Palmer area or camp at the Spotted Tiger Camp ground you will need to get a permit from the Northern Land Council (located in Alice Springs) as the camp ground is on aboriginal land and the access to the Mt Palmer area is through aboriginal land. There will be no problems getting the necessary permits. When I went to this area in June 2018 at the entrance to  the aboriginal land, past the race course on the access road, was a very large sign indicating you were about to enter aboriginal land and you needed the necessary permits to do so.
